COMMERCIAL  FERTILIZERS 

By  p.  L.  HIBBARD 


This  bulletin  comprises  the  results  of  the  fertilizer  inspection  work 
of  the  California  Fertilizer  Control*  for  the  fiscal  year  ending  June  30, 
1919. 

PURPOSE  AND  FUNCTIONS  OF  THE  FERTILIZER  CONTROL 

The  duty  of  the  Fertilizer  Control  is: 

First:  To  issue  certificates  of  registration  to  manufacturers  and 
dealers  who  have  complied  with  the  law  by  filing  a  sworn  statement  of 
composition  and  sources  of  the  fertilizers  they  wish  to  sell. 

Second:  To  analyse  these  fertilizers  as  found  in  the  open  market 
and  publish  the  results  for  the  information  of  the  public.  If  a  manu- 
facturer sells  fertilizers  which  are  materially  below  his  guarantee  in 
composition  or  value  he  is  subject  to  prosecution  and  fine.  By  this 
means  it  is  intended  to  insure  to  purchasers  that  the  fertilizers  they  buy 
shall  be  substantially  as  good  as  represented. 

By  a  study  of  the  reports  of  analyses  of  fertilizers,  the  consumer 
should  be  able  to  determine  whether  the  materials  he  buys  are  sold  for 
a  fair  price,  and  whether  he  obtains  fertilizers  of  the  desired  composi- 
tion. In  short,  the  function  of  the  Fertilizer  Control  is  to  see  that  the 
manufacturer  gives  the  consumer  a  square  deal. 

MAINTENANCE  OF  GUARANTEES 

Every  manufacturer  is  required  by  law  to  guarantee  the  percentage 
of  nitrogen,  phosphoric  acid  and  potash  in  the  fertilizers  he  sells.  Owing 
to  difficulties  of  sampling  and  analysis  the  law  permits  a  maximum 
deficiency  of  0.25%  nitrogen,  1.00%  phosphoric  acid,  and  0.50%  potash 
from  the  figures  guaranteed.  Greater  deficiences  than  these  are  re- 
garded as  infractions  of  the  law  and  are  indicated  in  the  report  of  analyses 
in  black-faced  type. 

Some  manufacturers  uphold  their  guarantees  better  than  others. 
The  following  table  is  a  condensed  report  of  the  deficiencies  found  in 
the  main  table  of  analyses.  It  summarizes  the  work  done  in  this  labora- 
tory on  each  manufacturer's  goods.  The  columns  headed  Deficiencies — 
-per  cent,  of  -possible,  may  be  used  for  comparison  of  the  various  com- 
panies  as   to   probability   of   meeting   their   guarantees.     The    other

approved  March  20,  1903.

UNIVERSITY    OF    CALIFORNIA EXPERIMENT    STATION 


columns  are  necessary  to  show  how  these  figures  were  obtained.  In 
cases  where  very  few  analyses  are  reported  for  a  manufacturer,  the 
figures  should  be  taken  with  caution,  as  perhaps  not  properly  repre- 
sentative. When  several  samples  of  one  manufacturer's  goods  were 
analysed  the  figures  may  be  accepted  as  probably  a  fair  indication  of 
the  reliability  of  his  guarantee. 

In  general,  manufacturers  have  more  than  maintained  their  guaran- 
tees, so  that  an  average  of  all  the  analyses  would  show  a  substantial 
increase  over  the  amount  guaranteed.

Owing  to  the  possibility  of  misunderstanding,  the  figures  for  percentage 
deficiences  are  not  given  in  above  table  in  cases  where  less  than  four  samples 
were  analyzed. 

Fertilizers  sold  on  Station  analysis,  and  some  others,  are  not  given  a 
valuation  in  the  table  of  analyses,  hence  the  number  of  such  samples  is 
deducted  from  the  total  number  analyzed,  in  computing  deficiences  in 
valuation. 


Bulletin  315  COMMERCIAL  fertilizers  199 


SUMMARY  OF   DEFICIENCIES 

In  the  analyses  of  the  above  samples,  the  following  number  of  defi- 
ciencies greater  than  those  allowed  by  law  occm'red: 

Available  phosporic  acid  (total  when  available  is  not  guaratneed) 9 

Total  nitrogen •. 31 

Potash 5 

In  Valuation ^ 14 

These  deficiencies  were  found  in  41  samples. 

Of  the  total  number  of  valuations  reported  in  this  bulletin  68%  are 
above  the  amount  guaranteed  while  32%  fall  below. 

MECHANICAL  CONDITION  OF  FERTILIZERS 

A  good  degree  of  fineness  is  one  of  the  essential  qualities  of  a  good 
fertilizer.  It  may  be  assumed  that  the  finer  the  material  the  higher  the 
availability,  hence  the  consumer  should  insist  on  having  finely  ground 
fertilizers.  Unfortunately,  some  manufacturers  are  at  times  careless  in 
regard  to  the  fineness  of  their  goods.  The  insistent  demand  of  the  con- 
sumer is  the  most  effective  means  of  correcting  such  carelessness. 

Besides  the  low  agricultural  availability  and  the  difficulty  in  apply- 
ing coarse  fertilizers,  it  is  almost  impossible  to  obtain  adequately  repre- 
sentative samples  of  such  goods  for  analysis.  This  is  a  prolific  source  of 
dissatisfaction  and  disagreement  between  buyers  and  sellers.  During 
handling  and  transportation  a  coarsely  ground  tankage  will  separate  so 
that  the  top  of  the  sack  contains  the  coarser  material,  high  in  nitrogen, 
while  the  bottom  contains  the  finer  parts  of  bone,  high  in  phosphoric 
acid.  A  mixture  of  coarse  bone  meal  with  sulfate  of  potash  will  separate 
into  coarse  bone  at  the  top  and  excess  of  potash  at  the  bottom. 

One  of  the  chief  reasons  for  the  existence  of  the  fertilizer  manu- 
facturer is  that  he  is  better  prepared  than  the  farmer  to  grind  and  mix 
the  goods  he  sells,  and  the  farmer  should  insist  that  he  do  it  well. 

CAUTION  IN  REGARD  TO  LABELING  FERTILIZER  PACKAGES 

The  law  expressly  states  that  every  package  of  fertilizer  shall  be 
accompanied  by  a  plainly  printed  label  giving  the  brand  name,  analysis, 
and  source  of  the  materials  in  the  package.  This  requirement  is  not 
satisfactorily  met  by  some  manufacturers  and  dealers.  Farmers  are 
hereby  cautioned  that  if  they  buy  improperly  or  inadequately  labeled 
fertilizers  or  goods  not  sold  by  properly  registered  dealers  or  their 
authorized  agents  they  lose  the  protection  afforded  by  the  Fertilizer 
Control.  Consumers  should  insist  that  fertilizer  tags  show  plainly  both 
the  percentage  and  the  derivation  of  each  ingredient.     A  verbal  state- 


200  UNIVERSITY    OF    CALIFORNIA EXPERIMENT    STATION 

ment  given  by  selling  agent  should  not  be  accepted  as  adequate.  The 
honest  manufacturer  is  willing  to  guarantee  his  goods  properly,  and  the 
farmer  will  best  serve  his  own  interests  by  dealing  with  no  other. 

FERTILIZER  VALUATIONS 


One  per  cent,  of  a  ton,  20  pounds,  is  called  a  unit."  Computation 
of  the  value  of  a  fertilizer  is  simplified  by  use  of  the  ^'unit."  To  find 
the  commercial  value  of  a  fertilizer,  multiply  the  per  cent,  of  each  in- 
gredient by  the  price  per  unit  and  add  the  products.  The  sum  thus 
found  is  the  value  per  ton  at  the  prices  used.  If  it  is  desired  to  use  such 
calculations  for  determining  the  amount  which  should  be  paid  for  goods, 
or  the  rebate  to  which  the  buyer  is  entitled,  owing  to  the  goods  delivered 
being  below  the  guaranty,  it  can  only  be  satisfactorily  done  if  a  definite 
price  per  unit  has  been  agreed  upon  between  buyer  and  seller.  But 
for  the  mere  purpose  of  showing  the  relative  values  of  goods  to  guar- 
anties, it  is  not  at  all  necessary  that  the  prices  adopted  should  be  the 
exact  market  prices.  Thus  it  is  that  the  Fertilizer  Control  in  attempting 
to  show  the  relation  between  values  found  and  values  claimed,  uses  a 
schedule  which  is  admittedly  only  an  approximate  average  of  market 
values.  Owing  to  market  fluctuations,  differences  in  cost  of  delivery 
at  different  points,  and  other  causes,  it  is  impossible  to  obtain  true 
average  market  prices,  but  if  the  reader  will  bear  in  mind  the  true  pur- 
pose of  the  valuations  reported,  these  will  have  served  their  turn  and 
he  will  not  be  led  to  assume  that  the  experiment  station  is  dictating 
the  prices  at  which  fertilizers  shall  be  sold.

SCOPE  OF  INSPECTION 

During  the  year  240  samples  of  fertilizers  and  fertilizing  materials 
were  received  at  this  laboratory.  Of  this  number  10  were  sent  by 
farmers  under  the  two-dollar  fee  provision,  161  were  taken  by  inspectors 
from  purchasers'  goods  upon  the  request  of  the  purchasers,  and  46  were 
taken  by  inspectors  from  goods  in  the  hands  of  agents  and  manufacturers. 
23  samples  of  a  miscellaneous  nature  are  omitted  from  the  tables.

REGISTERED  MANUFACTURERS  AND   DEALERS 

The  following  manufacturers  and  dealers  in  commercial  fertilizers 
obtained  certificates  of  registration  under  the  provisions  of  the  Cali- 
fornia fertilizer  law,  for  the  fiscal  year  beginning  July  1,  1918.  A  list 
is  also  given  of  the  brands  of  fertilizers  and  fertilizer  materials  offered 
for  sale  by  them.  According  to  the  sworn  returns  of  dealers  registered 
for  the  fiscal  year  ending  June  30,  1918,  their  entire  sales  in  the  state 
amounted  to  32,036  tons.  Incomplete  returns  for  the  year  ending 
June  30,  1919,  indicate  approximately  42,000  tons. 

No  dealer  or  manufacturer,  except  those  who  have  certificates  of 
registration  from  the  University  of  California,  and  their  authorized 
agents,  can  legally  sell  fertilizers  in  this  state.  No  person  or  company 
has  any  right  to  use  any  registration  number  except  in  connection  with 
the  firm  name  to  which  the  registration  certificate  of  such  number  has 
been  issued;  and  no  person  or  company  to  whom  a  registration  number 
has  been  assigned  has  any  right  to  allow  any  other  person  or  company 
to  use  said  registration  number;  any  number  so  used  is  a  fraud.  No 
agent  has  a  right  to  use  his  principals'  registration  number  in  connection 
with  his  own  name.

REPORT  OF  ANALYSIS 

Available  phosphoric  acid  is  not  determined  in  bone  meal,  tankage, 
and  Thomas  phosphate  powder,  unless  requested.  The  fineness  of  these 
materials  is  determined,  fine  and  medium  bone  being  separated  by  a 
sieve  of  50  meshes  to  the  inch ;  tankage  by  a  25-mesh  sieve ;  and  Thomas 
phosphate  powder  by  a  100-mesh  sieve. 

Nitrogen  in  ammonium  salts  will,  in  some  cases,  be  found  reported 
when  nitrogen  in  this  form  is  not  guaranteed.  In  some  of  such  cases 
this  form  of  nitrogen  is  produced  by  conversion  of  organic  nitrogen 
during  process  of  manufacture,  and  is  not  to  be  considered  a  deviation 
from  guaranty  of  materials  used.  Guanos  carry  more  or  less  nitrogen 
in  nitrates  and  ammonium  salts,  and  when  any  appreciable  quan- 
tity of  guano  is  used  the  manufacturer  should  take  into  account  the 
fact  that  some  nitrogen  will  show  as  nitrates  and  ammonium  salts. 
The  failure  to  take  this  into  consideration  may  account  for  the  appear- 
ance of  these  forms  of  nitrogen  in  some  samples  in  which  only  organic 
nitrogen  was  guaranteed. 

The  percentage  of  chlorin  is  given  when  it  exceeds  0.50  per  cent. 
It  is  a  matter  of  only  technical  interest  whether  chlorin  present  is  from 
muriate  of  potash,  kainit,  or  from  common  salt  that  may  be  in  some  of 
the  materials  used.  If  a  manufacturer  uses  sulfate  of  potash  and  a 
tankage  with  it  containing  a  large  amount  of  chlorin,  from  a  practical 
standpoint  he  has  changed  the  quality  of  his  fertilizer  just  as  much  as 
if  he  had  used  muriate  of  potash  instead  of  sulfate  of  potash.  Chlorin 
from  all  other  sources  has  the  same  effect  as  if  from  muriate  of  potash. 
However,  if  muriate  of  potash  is  found  when  sulfate  is  guaranteed,  the 
fact  will  be  published. 

The  following  abbreviations  are  used  in  the  tables:  Bat  G  =  bat 
guano,  Bl  =  blood,  Bn  =  bone,  Fs  =  fish,  G  =  guano,  H  =  hoof,  Min. 
Phos  =  mineral  phosphate.  Super  =  superphosphates,  T  =  tankage,  GSM 
=  cotton  seed  meal. 

Guarantees  are  entered  in  italics.  Deficiencies  greater  than  those 
allowed  by  law  are  entered  in  bold-faced  type.
